GOLF-CLUB.

Specification of Letters Patent.

Patented Jan. @5, rain.

Application filed April 13, 1915. Serial No. 21,078.

To all whom it may concern:

Be it known that l, .WILLIAM HENRY ME- GUYER, subject of the King of Great Britain, residing at Forest View, Cliff Road, Cowes, llsle of Wight, England, Great Britain, have invented certain new and useful Tmprovements in Golf-Clubs, of which the following is a specification.

The invention relates to a golf club shaft formed by a length of steel tube.

Such a shaft has been made taper, and partly taper and partly parallel, and also wholly parallel, and with walls of uniform thickness or of different thicknesses at different parts, withthe objects of giving to the shaft the correct weight, a proper balance', and the necessary strength, and also a transverse resiliency or spring, the idea being to provide a shaft in substitution for the ordinary hickory one. Such a metal shaft lacks one very important feature, namely, the necessary effective torsional or twisting resiliency or spring, and the object of the invention is to provide said shaft with such torsional or twisting resiliency, or'

spring, and at the same time increase, or render more effective, its transverse resiliency' or spring.

According to the invention the shaft is made of a length of tempered steel tubing, slit or formed with openings at any place or position to enable said shaft to have the necessary effective torsional or twisting resiliency or spring in addition to the transverse resiliency orspring. Same may be carried out, for instance, by slitting or cutting openings at suitable places in a weldless steel tube or in a welded steel tube, or by forming the tube length open-jointed and then closing the joint at diflerent places,

said slits or openings being either parallelor tapering, or straight, the tubular length being either straight, taper, or partly taper, or partly parallel, and either of a uniform gage of metal or of different gages at different parts in its length. The drawings forming part hereof illustrate various examples of arranging said slits or openings in a tubular shaft.

Figure 1 is an elevation of a club with the invention applied. Fig. 2 is an elevation of a portion of a shaft length used in Fig. 1. Fig. 3 is an elevation of the same length drawn to a larger scale. a transverse section of Fig. 2.

In Figs. 1 and 2 the scale of the drawing is so small as not to permit of the space of the openings being clearly shown, which oppnings are therefore represented by a line on y.

The shaft length is formed from a weldless steel tube drawn taper from end to end, and in its application tothe club its handle end a is wrapped with a grip and its other end, as usual, is fitted into a club head (if.

The slits or openin s are diagrammatically indicated at 0, same extending longitudinally of the tube length but in staggered formation, commencing at d and ex tending to near the handle, said slits being shortest in length farthest away from the handle end and increasing in length toward the handle end. The slittings form definite openings, as clearly represented by the larger longitudinal representations, and these openings impart to the shaft efiective torsional spring not obtainable from any particular part of the shaft alone but from a considerable length of the shaft, the longer slittings being at larger diameters of the shaft or farthest away from the club-head Fig. 4: is

end of the shaft. On impact the torsional resiliency in the shaft is obtained from the whole of the slittings or piercings, which open and close slightly in the twist, and in such manner as to obtain the spring from a considerable length ofthe shaft.

Figs. 1 to 4: show how the openlngs c are in staggered positions, same at the ends being enlarged as at 0 to prevent all tendency of the tube length to split.

Having now described my invention what I claim and desire to secure by Letters Patent is A golf club comprising, a tubular shaft substantially cylindrical in cross section and forme'd with a plurality of slits therein arranged in staggered relation.

In testimony whereof ll have hereunto set my hand in presence of two subscribing witnesses.
